Title: An improved process and apparatus for extracting starch or other like materials from substances containing such materials
IPC: C08B30/04
Filed: 1937-06-28
Abstract: <PICT:0497243/IV/1> Starch or other material of like density and grain size is separated from liquid in which the material is suspended by passing the liquid upwardly within an inclined tubular structure, fresh water entering below the place of entry of the said liquid passing up through the material precipitating from the liquid. The velocity of the fresh water is equal to or less than the velocity at which the particles fall.  In the manufacture of starch from potatoes, the tubular structure 1 is filled with fresh water, and potato pulp, diluted with water, is introduced through pipes 3. Fresh water introduced through pipe 5 passes into inclined hollow plates 4, and passes up through the perforated upper surfaces thereof.  The starch which settles on the inclined plates 2 slides downwards and passes over the hollow plates 4. The starch sediment is kept in a movable state by the agitator 7 until it is withdrawn through pipe 6.  The process may also be applied to the treatment of starch milk or of a suspension of coagulated albumen.  For example, the albumen in the fluid passing out through pipe 9 may be coagulated, and the fluid similarly treated to separate the albumen.
